No on free ESXi 4.1 jumbo frames?

Similar Questions

• ESXi 5 and Jumbo frames

  What is the proper way to configure some jumbo frames for an ESXi cluster used shared storage NetApp?  Configure extended frames to the bottom of the VM Guest NETWORK card or I stop at the dvSwitch?  I already configure jumbo images throughout the storage on the physical hardware.  It's just the virtual machine where I'm not sure and if I do not set up the virtual machine, will there be problems?

  Thank you!!

  Then, you don't need to do anything for the virtual machines.

• ESXi 4 has Jumbo frame support?

  I am about to install a "Iomega StorCenter Pro ix4-200r NAS' for use with a server ESXi 4 using iSCSI.

  This device supports Jumbo frame support and hoping that ESX does as well, anyone know?

  Thank you

  I'm not sure I understand how to make a big gain - with 1500 byte MTU, it's already better than 97% (38-byte header).  Of course, there will be a reduction in the treatment of overhead (CPU utilization should be reduced a little) but toe should alleviate a lot of this - ESX (i) uses ToE?

  Unfortunately the jumbo frames are a feature under license, see here.

• Broadcom 57711 + ESX/ESXi 4.1 + Jumbo frames

  Having a few problems getting Broadcom 57711 NIC working on ESX/ESXi 4.1 with MTU 9000.

  ESX/ESXi 4.0 U2 I have no problems to do and work MTU 9000 and I can push our strong enough EQL PS6010 SAN get 550 000 kbit/s with e/s meter runs inside 4 x VM.

  I read the documentation and found that an MTU of 1500 is supported only for the NIC in ESX/ESXi 4.1 57711. It has somethig to do with the fact that these cards have hardware iSCSI unloading, there is additional iSCSI adapters that appear under the storage adapters heading 4.1 hosts.

  I everything configured properly with 1:1 binding maps iSCSI network to ports VMK iSCSI with an MTU of 1500. When configured, this is the max that I can get out the SAN is 280 000 kbit/s. If I try the same process using the virtual machine a MTU of 9000 / host appears to stop responding.

  While I understand that it is a limitation of 1500 when using iSCSI NIC hardware I am unable to get the iSCSI Software to work with a MTU of 9000 on ESX/ESXi 4.1. If I try the software iSCSI using a MTU of 9000 of the VM / host appears to stop responding.

  Is also a limitation, or am I missing something.

  Is there anyone else out there has the same problems as me?

  Looks like a CD to update the Broadcom Driver (1.60.50.v41.2) was recently published in the area of downloads/drivers & tools vsphere.  I have not tried yet, hopefully, it will solve this problem.

• ESXi 4.0 and 4.1 Free Edition and Jumbo frames

  Hello everyone.

  Happy new year.

  Please can someone answer my question.

  Extended frames are not supported in the free ESXi 4.0 edition

  This is discussed here.

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1012454

  Are they supported in ESXi 4.1 Free Edition or should I upgrade to Essentials?

  Thank you very much

  James

  Extended frames are supported in ESXi 4.1. http://KB.VMware.com/kb/1023990 just not in the free version, at least through the vCLI.

• cannot ping vmk2 on other servers with jumbo frames

  I had 3 servers esxi 5.1 configure each with 2 NICs vmk - vmk1, vmk2

  vmk1 is on fabA

  vmk2 is on fabB

  the chassis is connected to the FI and the FI, its goes directly to the heart of nexus 7 k. Frames is enabled on the core switches.

  I have CoS of vmotion gold and a Qos policy of gold with the default values shown.

  the problem is each esxi host, when I try to vmkping (vmkping s 8000 vmk1 or ip vmk2), the vmk2 of another esxi host, it does not. but the fact of vmk1.

  I checked my vmnic political and especially on fabB models and they are all set to 9000.

  any ideas here?

  I ping the host local esxi itself and vmk1 vmk2

  Tony,

  One of the things to keep in mind is that traffic of FI - A IF-E passes by the upstream layer 2 network site.  Make sure the LAN past what uplink you also have enabled jumbo frames.

• Jumbo Frame (MTU) option is missing on vSwitch (vSphere Client)

  Hello.  We use ESXi 4.1 in our environment.  I'm going on my ESXi host configuration via vSphere Client, and found out that Jumbo Frame (MTU) is missing in the vSwitch.  That's what I expected, but the "NETWORK card" setting"section is missing.  Any of you had this problem?  Thank you.

  

  With ESXi 4.1 and versions earlier, you must configure several command line parameters, see for example http://kb.vmware.com/kb/1007654

• ISCSI enabling jumbo frames

  Hello world

  I want to just make sure I'm on the right track here.

  In theory, I should be able to enable jumbo frames 9000 on my switch and SAN without affecting guests. The scenario would be:

  • Stop all ESXi hosts
  • Reconfigure the SAN and switches to take in charge extended frames
  • Turn on ESXi hosts

  Basically, I want to make sure that the switches and SAN work correctly with change before changing anything on the hosts. Ideally, if all goes well with the hosts stable (vmkping d s 1500 x.x.x.x and turn VMs) I then change the MTU on the VMKernel ports and try again the hosts.

  Its good in theory?

  Sounds good to me, even if it is not necessary to stop the ESXi host. Stop the virtual machines should be sufficient.

• How to activate traffic iSCSI jumbo frames?

  Hi all

  I have my separate iSCSI coming out of a NETWORK card dedicated to one vlan traffic.

  Now, I have activated the switch to extended frames, qnas 869 pro for jumbo frames also and I (AFAIK) activated my extended frames ESXI host.

  However on the stats of the switch, I can't have counters increase jumbo frames.  others are but not huge.

  After reading all that I Although jumbo frames can help increase performance?

  So I appreciated if you could help me!

  Thank you

  Josh

  Well some how I made jumbo frames work on my ESXI host.

  I enabled frames for each unique interface on the ESXI host and on my NAS that provides iSCSI (qnap 869 pro), I enabled frames extended on both interfaces on it.

  Now it works no problem!

• Jumbo frames, change the MTU size without VM guest tension

  I'm trying to disable jumbo frames, specifically to change the size of the mtu to 1500 (instead of 9000) in vcenter on some hosts. Some hosts run esxi 4.1, others are running esxi 5.0. I wonder if it is absolutely necessary to turn off the virtual machines that are connected to the iscsi san network while making this change, or is it relatively safe to make this change, while VMS are running.

  Each VM has active multipathing, 2 vswitches with 1 NIC associated with each.

  I know how to make the changes, regarding my questions whether it is possible to safely make changes while VMS still access the SAN.

  Yes, it is something that I do in my lab quite frequently without using maintenance mode. Memaad notes, maintenance mode is always preferable to avoid unnecessary risks, but it's finally to you.

  See you soon.

• question of vMotion iSCSI and jumbo frames

  Hello

  I have a cluster ESXi 4.1 using vCenter and a SAN MD3200i.  I'll do an upgrade to optimize the installation, which includes the installation of four NIC ports in hosts that will be used for iSCSI.  I struggle to enable frames or not, but if I do, I just want to do for the iSCSI, at least for now.  Currently, the maps iSCSI network on the hosts and the MD3200 iSCSI connections are connected to two switches separated, although I have seven other switches in the building connected to the PC, printers, etc.  What I only turn frames on two switches that iSCSI is connected, or do I have to enable frames on all my switches?  There is a Dell 2724 and eight 6224Ps of Dell.  ISCSI is connected to the 2724 and one from the 6224Ps.

  The two switches that are connected to the iSCSI ports are not dedicated iSCSI switches; they have other devices on them, but I can only enable the frames extended globally on the switch.  Would there be any problem allowing the frames extended on the switches, otherwise all connected devices are configured for them?

  Another question about vMotion: I will create four ports on each host for iSCSI vmkernel.  Currently, there is also a port configuration vmkernel for traffic management and vMotion.  Is it possible to set up each of the four iSCSI for vMotion vmkernel channels, or should I leave it configured on the port of vmkernel management?

  Thank you!

  Sure. If you're going to enable Jumbo frames, you need to have dedicated switches for that, or a switch that may have different units MTU on their ports.

• Using jumbo frames rising more than 10 GB

  I have 2 10 GB uplinks that lead to the NFS, vMotion, virtual machine and all the traffic going to the host.  What is the best practice regarding jumbo frames?  If I use them to optimize the NFS traffic, it affects any other traffic as well as VM traffic so the production.   NFS should always use frames?

  TheVMinator wrote:

  It not there no problem to have certain groups of ports using frames and others using the regular size on the same host?  I just put the rest of the network to provide end to end?

  On the side of ESXi, there should be no problem. You have separate VLANs for different types of traffic? (Management, VM, NFS and other.)

• Validate the design of the network 2 x 10 GbE - NAS only 4 x 1 GB (jumbo frame)

  Dear Sir

  I have a few questions about the design of our new vSphere environment network.

  Detail:

  -Enterprise license

  -vSphere 5 servers (HP DL360p) with each:

  128 GB memory

  2 x Intel E5-2665 (8 cores)

  2 x 10 GbE (HP FlexFabric 554FLR-SFP +)

  -Environment NAS is connected via a LACP of 4 x 1 GB (no dedicated storage network)

  -Network environment is built on Juniper EX4200 is (virtual stack)

  Should / can use frames? :-)

  (a) servers, VMware will have 10 GbE and the storage network is only 4 x 1 GB?

  (b) this will give no problem for end-user connections that connect to the server VM

  running on the infrastructure as the file servers...

  Everything will not use frames but the will of the end user of PC, or is this not a problem?

  Is the picture below to go to the best?

  GRZ,

  Geert

  Honestly, there are a lot of discussions on when to activate the frames.  In my opinion I do not activate initially jumbo frames and watch the traffic.  If the backen was totally 10 GbE or FC, I would definietly enable Jumbo.  If necessary, then I would allow him.  Frames Jumbo will not affect the user who connects to the virtual computer, remember that they need to connect to the ESXi and not the current storage unit.

• VMware ESXi4.1 with Jumbo Frames on iSCSI (how to install?)

  Hello

  I've read various articles relating to ESXi 4.1 and frames. They all pretty much say the same thing. I'm having some trouble understanding step 3 in the section "Creating a Jumbo Frames - enabled VMkernel interface" in the link below. Could break you the order for me?

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1007654

  Step 3 says: to create a VMkernel connection with Jumbo Frame support, run the command:

  esxcfg-vmknic - a-i

  My stacked switches cisco 3750G are configured for frames.

  Thank you all. This is my first post.

  Mike

  Assuming you want to create a vSwitch separated with NIC dedicated to iSCSI traffic, you should do this:

  1.) create a new virtual switch, i.e.

  esxcfg-vswitch - an iscsi switch

  2.) enable Jumbo on this virtual switch, i.e.

  esxcfg-vswitch - m 9000 iscsi switch

  3.) create a port for the VMkernel module group

  esxcfg-vswitch - a GRPE-iscsi iscsi-switch ports

  4.) create VMkernel. You must specify an IP address for use with the VMkernel, and a network mask and the MTU size, i.e.

  esxcfg-vmknic - a-i 192.168.100.1 - n 255.255.255.0 m 9000 iscsi-portgroup

  5.) associate a physical NETWORK card with the new switch, i.e.

  esxcfg-vswitch - L VMNIC5 iscsi switch

  You must run the command-line jumbos steps since there is no GUI Option - at least none that I'm aware off the coast.

• Airport Extreme Gigabit Ethernet and Jumbo frames

  Hi all.

  Can anyone support me kindly about Gigabit Ethernet & Jumbo Frames with Airport Express?

  I currently have and use a 5th generation Airport Express and you want to buy the QNAP TS - 453 Pro NAS. In any implementation of storage NAS, Gigabit Ethernet, the frames extended as matching Ethernet card well, are all very important to achieve broadband performance, so my questions are:

  5th generation Airport Express

  
  

  • Are the NETWORK Gigabit NIC Ethernet card?
  • It also works with extended frames (QNAP NAS supports 4074, 9000 and 7418 bytes for MTU)?
  • QNAP can trunk NIC (if more then one) with the following options:
    • IEEE 802.3ad (dynamic link aggregation)
    • Balance-tlb (Adaptive Transmit Load Balancing)
    • Balance-alb (Adaptive Load Balancing)
    • others (mainly for failover)

  Is 5th generation Airport Express enough or should I think about moving to the 6th generation?

  Thank you.

  You mix up the terminology... Express and Extreme are totally different.

  The title is correct... Extreme... your question text replaces by Express... they are only 10/100... and gen only 2 of them.

  Any airport extreme Gen2 - Gen6

  Use the Gigabit ports.

  Do not support jumbo frames

  Do not support pairing.
